Textures Follow - The Geology of Ore Deposits (Guilbert and Park) Doc | Minerals | Rock (Geology)Applied Mineralogy pp Cite as. This chapter will deal with the formation processes of mineral deposits, i. Minerals are important because they contain most of the elements we use. All the minerals found in nature however do not fulfill this criterion. There are a number of factors which categorize a mineral as an economic one. The most important of these is that an economic mineral is needed to be easily extractable and economically viable.

Modern civilization's dependence upon an increasing volume and diversity of minerals makes the search for new ore deposits ever more difficult. The authors comprehensively describe the physical and chemical characteristics of ore deposits, and correlate them with environments and conditions of deposition since ore deposits are best interpreted as extensions of the environments responsible for their enclosing rocks. Examples and illustrations emphasize structural, chemical, and temporal controls and encourage the three-dimensional thinking used by productive explorationists as they face unsolved problems. This upper-level undergraduate text is fully illustrated and meticulously indexed. Its reliable, authoritative coverage assumes an upper-level command of chemistry and physics, as well as mineralogy, petrology, and structural geology.

ORE DEPOSITS 101 - Part 7 - VMS and Sedex
Textures vary among ore deposits, depending upon the nature of the mineralizing fluids, the physical and chemical characteristics of the host rocks, and the mode of emplacement. Textural interpretation can assist greatly in determining the time relationships of successive mineral assemblages in a rock, the overall environment of formation, and the manner of deposition. In epigenetic deposits, textures can help define the sequence and nature of events as in the complex vein shown in Figure , and they permit the distinction of mechanical and chemical controls as mentioned earlier in this chapter. In syngenetic depositssuch as sedimentary, volcanic-hosted, and mafic igneous onestextures may reveal accumulation rates and styles, cooling histories, and the nature of precipitation. Resorption of early formed crystals may produce peculiar textures in magmatic segregation ores Figures , , and , and diagenetic changes may modify the primary. The textures of hydrothermal ores tend to be diverse. Replacement As defined by Lindgren 1S33 , replacement, or metasomatism, is.
